[~guseinov], looks good overall. The only thing I've noticed is that you have not added new
test to MSVC solution. Check out the following files:

{{modules/platforms/cpp/odbc-test/project/vs/odbc-test.vcxproj}}

{\{modules/platforms/cpp/odbc-test/project/vs/odbc-test.vcxproj.filters}}

> This scenario should not lead an application crash. It seems we should throw an exception
like "Connection is closed" instead.
